Just a note...
I have a APC Smart-UPS XL 1000VA for my DLP, HR20, XBox360, and cheapy surround sound system, when all 4 are going at once, the load adds up.
I have the older version of the 300CS with my wife's laptop and a WAP on it. The load on that is normal.
Depending on what your TV, IRD and other devices pull, you might need a more powerful UPS
